    Need some help with a TRX 2.5

    I remember back in the late 90's ,my friends buy a different engine for more power ,the 1.5 was just way under power for the truck ,I think they was buying 16 & 18 size engines for them! But one of my other friend had that first gen 4-Tec street car an never had an issue with the 1.5 engine...

    Did you check for slop or play in the piston rod ,on the crank an in the piston? That is where the first things start to break down as those parts take the beating , those get sloppy ,an causes pre detonation an can snap a rod!

    What kind of plugs are you using?..🤔 Yes ,Losi 215 is right ,what he described could cause premature detonation an burn up plugs on top of bleeding fuel out of bearings ,check for wetness around the flywheel & chassy!..👍

    Need some help with a TRX 2.5

    My friend had bought a new Reds engine that had damaged & pinched carb o-rings ,it took him a long time to figure it out ,he didn't think the factory would screw them up!..🤣😂

    Need some help with a TRX 2.5

    How old or long has the engine been sitting? Possible that the o-rings are worn ,try screwing the lsn all the way in ,an counting the turns while you do ,then pull it out an rub some sticky grease on the o-rings an put it back in then run the truck! I will do a vid on a carb!..😎👍

    You can also do a pinch test after a full WOT run ,if the engine dies with in 2 seconds ,then its too lean ,if it dies with in about 4 seconds ,then you are spot on ,on the Lsn tune ,should be pinched just right at the carb nipple! Pinch test is not a tuning guide ,it only let's you know how...

    Need some help with a TRX 2.5

    For this reason ,is why it is hard to give info out on tuning ,tuning requires hands on ,sight ,sound plays a major role in tuning ,but yea if it is the lean bog ,then you are correct as it is a two way street on the tuning , you just have to figure out which one it is an monitor how many turns...

    Need some help with a TRX 2.5

    There is two things that can cause the bogging on take off ,either a lean bog or a too of a rich setting on the Lsn ,you just need to figure it out ,if your idle gap is set at .8mm ,you can close it a little more ,an lean the Lsn in a little more to raise the idle ,as this will cure the rich...

    You are probably almost there if the engine is staying running! Usually ,you are suppose to preset your idle gap to .5mm an adjust your Lsn to match it to idle an not match the idle gap to the existing Lsn mixter!..👍
